Why do we have lower acuity in very dim light?
A) The cones, which provide better acuity, are not sensitive to dim light.
B) Lateral inhibition is activated in very dim light.
C) Opponent processes cannot operate at low levels of light.
D) All of the above.

Cones are responsible for providing better visual acuity, but they are not as sensitive to dim light as the rods, which are responsible for providing better sensitivity in low light conditions. Therefore, in very dim light, we rely more on rods and have lower acuity. Lateral inhibition and opponent processes also play a role in visual processing, but they are not the primary reason for lower acuity in dim light.
